Description
Technical field
The utility model belongs to vacuum condensation boiler technology field, and in particular to a kind of low nitrogen vacuum condensation boiler.
Background technology
In the prior art, vacuum condensation boiler body lower part is hydrothermal area, and hydrothermal area is equipped with corrugated internal furnace, convection current screw thread cigarette
Pipe is restrained.Boiler body top is region of no pressure, and region of no pressure is equipped with heat exchanger.During boiler operatiopn, the flame handle in corrugated internal furnace
The hot water heating of boiler body lower part, produces steam under the pressure of -0.02MPa, passes through steam heater body top region of no pressure
Heat exchanger.The recirculated water in heat exchanger is absorbed heat and reach requirement temperature, steam is condensed into original hot water after heat release.
Vacuum boiler increases body dimension, increase convection current smoke pipe tube bank in the fabrication process to accomplish the end in view at present
Quantity.The increase of boiler manfacturing difficulty, especially oxynitrides (NOX) is so increased, advocating low nitrogen with country at present fires
Burning runs in the opposite direction.
Utility model content
In order to overcome the shortcomings of the prior art, it is insufficient to solve oxynitrides burning in existing vacuum condensation boiler
Technical problem, the utility model provides a kind of low nitrogen vacuum condensation boiler.
The utility model is achieved by the following technical programs：
A kind of low nitrogen vacuum condensation boiler, it is characterised in that：It includes boiler body, and the boiler body includes cylinder pot
Shell and bridge opening type condensing room, condensing room are fixedly installed on the top of cylinder shell, hydrothermal area are arranged to inside the cylinder shell；
Filled with heat exchange condensed water in the hydrothermal area, the bottom of hydrothermal area is provided with corrugated internal furnace, and the four of corrugated internal furnace
Week is arranged in parallel with convection current threaded flue along hydrothermal area's axis direction, and some convection current threaded flues form convection current threaded flue pipe
Beam, the exhanst gas outlet of corrugated internal furnace are connected with the gas inlet that convection current threaded flue is restrained, the flue gas of convection current threaded flue tube bank
Export and connected with the air inlet of rear smoke box on corrugated internal furnace；Along the axis side of hydrothermal area on cylinder shell at the top of the hydrothermal area
To being arranged in parallel with some through holes；
The condensing chamber interior is arranged to region of no pressure, and heat exchanger, condensing room leakage fluid dram and cylinder pot are provided with region of no pressure
The inlet connection of shell.
Further, the condensing room and cylinder shell separately manufacturing, and condensing room is welded in the top of cylinder shell.
Further, the through hole is arranged in parallel with 8, and through hole is strip, and the length of through hole is 800mm, through hole
Width is 20mm.
The utility model has the advantages that compared with prior art：
The utility model is able to ensure that fuel combustion abundance, and the oxynitrides content after burning in flue gas emission is by 200
~300mg/m3It is reduced to 100mg/m3Left and right；On the other hand, the utility model integrates boiler and heat exchanger, can maximum limit
The reduction boiler volume of degree, greatly reduces the spatial area shared by boiler so that user save boiler room floor space and
Capital expenditure；Meanwhile the system can coordinate central air-conditioning heating or domestic hot-water supply also can heating supply domestic hot-water at the same time.
A kind of low nitrogen vacuum condensation boiler provided by the utility model possesses simple processing, manufacture rationally, burning abundance,
The characteristics of low azo-cycle is protected.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is the left schematic cross-sectional view of Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 21, a kind of low nitrogen vacuum condensation boiler, it is characterised in that：It includes boiler body, described
